BOTTLE 0R- JAR CLOSURE.

Specification of Letters Patent.

Patented Oct. 22, 1912.

Application filed May 17, 1912. Serial No. 698,042.

To all whom 'it may concern:

Be it known that I, vvOLFF KOUFMAN, a citizen of the United States, residing at Paterson,'in the county of Passaic and State of New Jersey, have invented new and useof milk bottle and which will be provided with a swinging closure which may be adjusted to opened or closed positions at the convenience of the operator.

Another object of the invention is to provide a device of this character which will be so constructed that it can be applied to the bottle with the exercise of but little manual effort. A still further object is to provide swinging closure upon the neck of the bottle which will include an elastic member such as a body of cork or the like which when in its closed position will prevent the milk from flowing in contact with any metal parts of the device and which will also. serve through its frictional contact with the inner walls of the neck to form a perfect liquid tight connection.

. Another object of the invention is to provide a closure which will include a supporting member having a keeper recess orpassage therein anda springy retainer on the closure adapted to engage in the recess so as to hold the closure in its closed position.

Another object of the invention is to provide a retainer with a protruding manipulating portion which will extend beyond the keeper recess to permit of its being grasped between the fingers of the operator when it is desired to move the closure to an opened position.

In the drawing forming a portion of this application, and in which like letters of reference indicate similar parts in the several views-:.-I* igure 1 is a perspective view of a portion of amilk bottle showing the application of the bottle closure thereto. Fig. 2is a similar view showing the closure in an opened aosition. Fig. 3 is a vertical section theret rough showing the closure in a closed position.

The device comprises a lid or closure sup port 1 which is split vertically as at 2 whereby the support may be conveniently sprung and arranged in'embracing relation upon the neck of the bottle. The support is provided with a lower depending portion 4 which embraces the neck A of the bottle below the bead or enlarged upper portion B of the neck, and an upper concavo-convex portion 5 which peripherally embraces the said bead B of the neck. The walls of the portion 5 are extended above the plane of the bead B as at 6 and hinged to the extended walls as at 7 is a metallic disk 8. This 'disk is provided with a springy retainer- 9 which extends down against one side of the disk, being spaced therefrom and bent upon itself to provide a lower looking portion 10 and an. upper vertically extending manipulating port-ion 11. Immediately above the bead B the portion 5 has formed therein a keeper passage 12 which is adapted to receive the locking portion 10 of the retaining member as clearly shown in Fig. 3 whereby the closuredisk will be securely held in a closed position, the frictional engagement of the portion 10 with the walls of the passage 12 being sufficient to hold the former against accidental movement in the latter.

With a view to properly sealing the bottle and for preventing the milk or the contents of the bottle from coming in contact with any metal parts of the device I provide a yieldable body or plug 13 which is secured by fastening devices 14 to the underside of the metal disk 8. This plug is of circular configuration and it is adapted to fit. the interior walls of the neck A and to have such frictional contact therewith as will prevent leakage at this point.

I Vhile the body 13 is preferably constructed of cork itis evident that any other well known non-corrosive element may be substituted therefor without departing from the spirit of the invention.

The concavo-convex portion 5 of the 010-- sure support 1 engages in such manner he neath the lower walls of the bead B that the latterwill form a stop to prevent the upward movement of the support upon the neck. Downward movement of the support upon the neck is prevented through the engagement of the portion 5 with the upper external walls of the .bead B and a depending integral'inner flange 1 5, the latter being adapted to rest upon the upper edge of the neck as shown in Fig. 3. t

The member 1 may be made of springy material to facilitate its attachment to the neck of the bottle and'to retain its proper shape and in order to properly secure the member to the neck I provide a fastening wire or equivalent means 16 which is passed around the flange 4 and which has its terminals intertwisted as at 17.

I claim 1. A closure for bottles, comprising a member split vertically throughout and adapted to embrace the neck of the bottle and to be sprung circumferentially therearound, means for securing the member to the neck, said member having a recess therein,

a disk pivoted to the upper end of the memher and adapted to be extended across the neck of the bottle, and a springy retainer forming a part of the disk and adapted to be extended into the recess to hold the disk in a closed'position, said retainer being proby it may be engaged by the hand and drawn upwardly to permit the disk to be adjusted to an open position, and a yieldable 'plug secured to the under side of said disk/ I v 2. The combination with a bottle, of a member embracing the neck of the bottle and having annular depending walls termina-lly seated against the upper edge of the neck, whereby to hold adjacent portions of the member'spaced from the neck, the said member having a recess therein disposed above the plane of the neck, a disk hinged to the member and provided with a retaining portion adapted to be extended into said recess, whereby to hold the disk in a closed position, and a yieldable plug carried by the disk and adapted to be extended into. the neck of the bottle when the disk is in a closed position.

In testimony whereof I aflix my signature in presence of two witnesses.

WOLFF KQUFMAN.
